Good thought. We try to avoid obstacles to quick POC installation, but that has merit.

I would also advise to not use key0 for any of your application memory unless absolutely necessary. Have you considered a PPT entry for your jobstep program so that your code could get assigned to something like key2 or key4 ? Depending on what your application does, you might be able to achieve your design goals without having to ever switch keys out of key2/4. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
